The silicon carbide element (OEM part 1176919) glows to roughly 2,500°F to ignite the burner gas on each heat call, and the kit includes the dedicated igniter mounting bracket (OEM part 1183455) plus the snap-action HSI valve component (OEM part 1176929, ref 36J24618). When an igniter fails, the furnace blower may run but produce no heat, the unit will short-cycle on failed ignition lockout, or you may hear repeated clicking from the control board attempting ignition retries. Silicon carbide igniters are fragile and degrade with every heating cycle, so they are one of the most common no-heat failure points on this furnace platform.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1176919 (Igniter), 1183455 (Bracket), 1176929 (HSI Valve)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElement\u003c\/td\u003e\n\u003ctd\u003eSilicon Carbide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP (Tempstar \/ Heil \/ Comfortmaker)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eGas Furnace Ignition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM — Model WFMR045A024B1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct OEM replacement for the ICP Tempstar\/Heil WFMR045A024B1 furnace.
